RE: Pi Approximation Day
That's rather a good idea Albert!

About these various offerings for more efficient calculation of pi - I feel they miss the point a little bit. I think - for me - the appeal of Valentin's offering comes from the rather small number of terms to get the recognisable first few digits, and the clever hiding of the 10 as a loop counter.

I've run this formula of Ramanujan on various systems with various kinds of floats... the long double precision on Raspberry Pi 4 takes some 275000 terms to converge, giving about 30 digits of pi.
